Long-term Recordings of Arcuate Nucleus Kisspeptin Neurons Across the Mouse Estrous Cycle
The arcuate nucleus kisspeptin (ARNKISS) neurons represent the GnRH pulse generator that likely drives pulsatile gonadotropin secretion in all mammals. Using an improved GCaMP fiber photometry system enabling long-term continuous recordings, we aimed to ...

[Endocrine mechanisms of the synchronization of the estrous cycle in sheep].
Prostaglandin of the F2-alpha group (estrophan) led to a sharp decrease in serum progesterone concentration of 90-96% of Edibai female sheep eliminating the blocking hypothalamic center effect of the endogenous steroid hormone. The resultant conclusion was a possibility of artificial insemination of the above number of female sheep without finding out ...

Ictal activity is sustained by the estrogen receptor β during the estrous cycle
Catamenial epilepsy, defined as a periodicity of seizure exacerbation during the menstrual cycle, affects up to 70 % of epileptic women. Seizures in these patients are often non-responsive to medication; however, our understanding of the relation between

New Tools for Estrous Synchronization – Costs and Benefits
Estrous synchronization has become a powerful tool in managing breeding seasons to compliment niche markets. Synchronization of estrus, along with the use of AI, has become a popular technology that can introduce new sire genetics along with control of ...

A Comparison of Three Estrous Detection Management Schemes for Dairy Heifers
Heifers should represent the greatest genetic potential within a dairy herd. To maximize this potential, heifers must be inseminated to proven sires, a practice requiring management changes on many dairies.

A Novel Estrous Synchronization Program for Beef Cattle Using Melengestrol Acetate
Estrous synchronization rate and conception and pregnancy rates to AI were evaluated following three estrous synchronization protocols for beef cattle. During 1995 and 1996, heifers and cows (n = 379) received either: 1) melengestrol acetate (MGA) for 18
